Catalysis breakthrough yields self-cleaning wall paint that breaks down air pollutants when exposed to sunlight

Typically, beautiful white wall paint does not stay beautiful and white forever. Often, substances from the air accumulate on its surface. This can be a desired effect because it makes the air cleaner for a while—but over time, the color changes and needs to be renewed. A research team from TU Wien and the Università Politecnica delle Marche (Italy) has now succeeded in developing special titanium oxide nanoparticles that can be added to ordinary, commercially available wall paint to establish self-cleaning power: The nanoparticles are photocatalytically active, they can use sunlight not only to bind substances from the air, but also to decompose them afterwards. The wall makes the air cleaner—and cleans itself at the same time. Waste was used as the raw material for the new wall paint: metal scrap, which would otherwise have to be discarded, and dried fallen leaves. The study is published in ACS Catalysis.

SOLUSI LARI DARI POLUSI

Judulnya nampak berbobot, padahal isinya... tentu tidak.

Semenjak ramai sekali berita tentang buruknya polusi di Jakarta & sekitarnya, tadi pagi pas lagi nemenin Umar naik sepeda, disempatkan menatap langit lebih seksama dari biasanya. Alhamdulillah masih biru, walaupun sebagain lainnya berkabut, gunung (entah apa) yang biasanya nampak, ga nampak pulak tadi. Mengutip kata favoritenya Umar belakangan ini, "oh my god", ternyata nyata adanya polusi udara seburuk ini. Tapi, tahukan kita? Bahwa kendaraan menyumbang 30% dari total polusi di Jakarta, selebihnya PLTU dan sisanya yang lain-lain. Ini fyi ajasi. Tentu, tidak ada solusi praktikal untuk info diatas, dari saya. Ntar lah, kalau ada kesempatan jadi caleg partai, baru dipikirin solusinya😌 hehe.

Ohya, tadi setelah mengamati langit, ku wa lah suami. Bilang, sedih juga sama polusi ini. Suamiku sungguh sangat visioner, dia balas, "nanti kita beli rumah aja di Bandung, daerah Setiabudi/Ledeng". Mantap kali kan? Solusi yang diberi tidak tanggung-tanggung. Yaa, tapi setelah dipikir, Bandung kota juga mungkin akan makin padat kedepannya, jadi gimana kalau kita cari di Ciparay/Cililin aja? Tapi itu, jauh entah antah, gimana pulak kalau tiba-tiba ingin jajan di Gempol? Hm. Apa daerah Cigugur Girang/ Gerlong aja kalau gitu? Aamiin aja dulu dari sekarang.

Jadi, solusi lari dari polusi nih, nampaknya kita hijrah tempat tinggal aja gitu ya? Jadi, bagus dong agenda pemerintah sekarang ini yang mau pindah ke IKN? Mantap. Jaya selalu Pakde dan Pak Luhut👍 lah.... wkwk.

Yaudahlah, mana sini yang punya info rumah dijual di Bandung kota agak minggir dikit, yang daerahnya ga macet, masih hijau, masih ada sejuk dingin-dingin enak, fasum lengkap, tapi harga dibawah 600an🙃 hehe. Sungguh banyak ingin, minim modal. Seperti para caleg politik yang balihonya membuat mata perih👌

Jadi, solusi tercepat dan termurah untuk saat ini adalah: Yuk, kita beli air purifier! Selamatkan udara di dalam rumah dulu, seengganya kan. Apa ini sudah waktunya, ngeshare link shopee?😌

Network Failure

October 2021 saw the biggest communications outage in history. Facebook went down. Although the disruption only lasted six hours, it caused worldwide chaos and cost Mark Zuckerberg $6 billion. Researchers have discovered that our brains experience similar network failures in response to bisphenol A. We’re exposed to this chemical every day – it’s in food packaging, shopping receipts, and medical equipment. Here, we see neurons (black) from mice exposed to bisphenol A for two months. Compared to untreated cells, the number of dendritic spines on these neurons decreased by 42%. These long thin structures allow neurons to talk to each other, and are vital for learning and memory. Mice exposed to bisphenol A suffered from anxiety and disrupted memory processing, and the scientists have uncovered how the chemical causes these changes to the brain’s network. This work explains how a ubiquitous chemical can disturb our brains, supporting efforts to regulate its use.

Brown Rown looks forward to a day of play. That large nose of his sure gets in the way. A hanky danky is what he needs to catch the kerchews he does sneeze. Through a park and around a slide he rides his bike with a map on his side. Some trash is found along the way. He picks it up throughout the day.

Brown Rown is a cute little guy who will teach your child to be mindful of the environment and pick up after themselves.

Bayer and Monsanto Settle with Oregon

Bayer and Monsanto Settle to Pay Oregon for PCB Pollutants

Bayer and Monsanto have settled a lawsuit with Oregon, agreeing to pay the state almost $700 million over PCB pollution allegations. Polychlorinated biphenyls (PCBs) are toxic compounds formerly used in many applications, from coolants to copy machines and fluorescent light bulbs. Monstanto is the only company ever to manufacture PCBs in the United States, a factor which helped lead to their…

Pteris vittata, aka Chinese brake, ladder brake, or Chinese ladder brake, is the first plant identified to be able to hyperaccumulate arsenic and reduce its quantities in soil. Scientists have been proposing for a while that this fern could be useful in phytoremediation (extracting and removing/reducing the amount of elemental pollutants in soil).

(CNN) -- The US Environmental Protection Agency issued health advisories Wednesday for common "forever chemicals" that are found in hundreds of household items and pollute drinking water systems across the country.

The update is based on the most recent science, which suggest that these chemicals are much more hazardous to human health than scientists had thought and are probably more dangerous at levels thousands of times lower than previously believed.

This PFAS family of synthetic chemicals remains in the environment and in the human body for a long time, as the "forever" name implies.

There are hundreds of chemicals in the family, but some of the best-known are PFOS and PFOA.

Science has found that exposure to PFAS can lead to serious health problems. Exposure is linked with liver damage, thyroid disease, diabetes, decreased fertility, kidney problems, high cholesterol, obesity, hormone suppression and cancer.

Starting in the 1940s, manufacturers widely adopted the use of PFAS because they are good at repelling oil and water. Their signature elemental bonds of fluorine and carbon are extremely strong, making it difficult for the chemicals to break down in the environment or in our bodies.

The chemicals can be found in Teflon nonstick products; water repellants on carpets, furniture and clothes; and paints, cleaning products, cosmetics, food packaging and firefighting foams.

Over the past decade, chemical manufacturers have voluntarily stopped producing PFOS and PFOA. At the federal level, the US Food and Drug Administration phased out the use of certain PFAS chemicals in 2016. The FDA and manufacturers agreed in 2020 to phase out some PFAS chemicals from food packaging and other items that came into contact with food. However, FDA monitoring of the environment showed that the chemicals tend to linger.

Testing by the nonprofit Toxic-Free Future found that 74% of imported products still contain older PFAS chemicals.

These chemicals can easily migrate into air, dust, food, soil and water. People can also be exposed to them through food packaging and industrial work.

PFAS has also been found in high concentrations at the country's military bases. The US Department of Defense says it has spent more than $1.5 billion on PFAS-related research and cleanup efforts.

In the body, the chemicals primarily settle into the blood, kidney and liver. A 2007 study by the US Centers for Disease Control and Prevention estimated that PFAS chemicals could be detected in 98% of the US population.

In 2016, the EPA recommended PFAS concentrations in drinking water of no more than 70 parts per trillion (ppt). The interim advisories updated Wednesday recommend no more than 0.0004 ppt of PFOA and 0.02 ppt of PFOS, so low that the chemicals cannot be reliably detected.

Also Wednesday, for the first time, the EPA issued final advisories for limits in drinking water of the PFAS chemicals GenX, considered a replacement for PFOA, and PFBS, a replacement for PFOS. It now advises less than 10 ppt for GenX and 2,000 ppt for PFBS.

"Today's actions highlight EPA's commitment to use the best available science to tackle PFAS pollution, protect public health, and provide critical information quickly and transparently," EPA Assistant Administrator for Water Radhika Fox said in a statement.

The advisories are not enforceable, but they could have an effect on drinking water rules and monitoring programs at the state and federal level. There are also thousands of lawsuits making their way through the courts against companies that used these chemicals.

The EPA said it is making available the first $1 billion of $5 billion in grant funding from President Biden's Bipartisan Infrastructure Law to help communities reduce PFAS in drinking water.

The American Chemistry Council, a group that represents the chemical industry, said Wednesday that the EPA failed to follow "its accepted practice for ensuring the scientific integrity of its process." In a statement, the association argued that the EPA should have waited for a peer review of the science to introduce these changes.

Water pollution from dyes used in textile, food, cosmetic and other manufacturing is a major ecological concern with industry and scientists seeking biocompatible and more sustainable alternatives to protect the environment. A new study led by Flinders University has discovered a novel way to degrade and potentially remove toxic organic chemicals including azo dyes from wastewater, using a chemical photocatalysis process powered by ultraviolet light. Professor Gunther Andersson, from the Flinders Institute for NanoScale Science and Technology, says the process involves creating metallic 'clusters' of just nine gold (Au) atoms chemically 'anchored' to titanium dioxide which in turn drives the reaction by converting the energy of absorbed UV light.
